Application May 26, 1939, Serial" No. 275,973

2 Claims.

My invention consists of metal roofing and fastening means therefor, which includes among its objects, the provision of preformed metal,

sheets or shingles engaged'to the roof andwith 5 one another in an especial manner, the roof engaging fastening means being completely protected from the elements thereby minimizing possibility of casual displacement of the sheets or shingles. d

It is also within the contemplation of my invention to equip the roofing sheets or shingles with suitable fastening appendages engageable with adjacent sheets to permit securement of the free margins of the sheets without the aid of extraneous fastening means.

A further embodiment of the invention is to provide sheets or shingles which include overlapping 0r interlocking adjacent terminals which may be secured together by fastening tabs, which latter may be independent of or an extension of the sheets.

Other objects of the invention will be apparent from the following description of the present preferred forms of the invention, taken in connection with the accompanying drawing, wherein:

Fig.1 is a perspective view of roofing and fastening means constructed in accordance with my invention, illustrating its application,

Fig. 2 is a detail fragmentary perspective view of a slightly modified form of my invention,

Fi 3 is a detail fragmentary plan view of a modified form of my invention,

Fig. 4 is a detail fragmentary sectional view taken on the lined-4 of Fig. 3, looking in the direction of the arrows, and

Fig. 5 is a fragmentary perspective view of a modified form of fastening strip.

To illustrate the application of my invention, I have in the drawing, shown a portion of a roof 40 6, which may be of any desired configuration. Also, to further illustrate the invention, I have-in Fig. l of the drawing, shown a portion of a ridge 1, which may be of conventional design.

Roofing formed in accordance with the present invention consists of sheets or shingles 8, formed of metal, each preferably, as shown in Fig. 1 of the drawing,'has one edge thereof reversely folded upon itself to provide a strip 9, the latter having its free margins serrated to provide truncated V-shape tabs Ill. The sheets or shingles may be of any desired size and con figuration, but are preferably formed substantially as illustrated in the drawing. It is also preferred that the sheets with the reversely folded strips 9 be pre-formed so as to be adapted for transportation in this condition, thereby avoiding the necessity of changing the conformation ofthe sheets or shingles on the job. It is of the essence of importance in the present invention that the fastening means employed be completely covered so as to avoid exposure, thereby preventing casual displacement of the sheets which is usually an incident to the. nails creeping from the metal shingles due to atmospheric changes. The method employed in nailing the 10 shingles eliminates the possibility of exposure of any of the fastening means. A preferred form of the invention, as shown in Fig. 1, illustrates the nails in which each fastening means is protected when in use. This embodiment of the 15 invention consists of tabs H, one of the marginal edges of each of which issecured adjacent the free or loweredge of the roof, the opposite margin extending appreciably beyond the roof edge. The roofing sheets 8 are then placed upon the roof so that the free edges thereof coincide or extend slightly beyond the edges of the roof. The adjacent terminals of the sheets are overlapped or interengaged, as generally designated at l2. The overlapped margin of each sheet is I provided with holes l3 through which nails or other suitable securing means may be passed for engagement with the roof 6. After this the free ends of the tabs II are folded over into engagement with the free margins of the sheets at the lower end of the roof, as shown at the right side of Fig. 1 and also in Fig. 2 of the drawing.

After the first tier or row of shingles has been secured on the roof, the next row is arranged so that the free margin of each single of the adjacent row overlaps the strip 9 of the first row extending only to the base of the tabs In, as shown in Figs. 1 and 2. The opposite margin of each sheet is secured to the roof as already herein described, in referring to the first row of shingles. 0 Pursuant to this one of the tabs Ill of the lower row, at predetermined intervals, is folded upwardly and into engagement with theadjacent row of sheets or shingles 8, as also illustrated in Fig. 1. This same procedure is followed until 45 the top or apex of the roof is reached, at which point it is preferred to provide independent tabs II which areof similar construction to the tabs H. The tabs H are preferably superimposed on the sheets 8 and fastened through the latter- 50 to the roof 6, by suitable fastening means. These tabs may then be folded upwardly into engager ment with the marginal edgesof the ridge 1 to secure the latter from displacement, as also shown in Fig. 1. It is to be understood that if desired,

instead of providing independent fastening tabs II, I may extend the tabs 10 of the opposite row of shingles to permit engagement of the extended tabs with the ridge.

In the form of invention illustrated in Fig. 2, instead of forming the strip 9 integral with the sheet 8, said strip indicated at 9', is preferably independently formed. This form of invention is desired where the roof is of insuflicient pitch making it necessary to overlap the roofing more than the standard distance employed in the form of invention illustrated in Fig. 1. With this form of invention, after the shingles 8 have been laid, the strips 9 aresecured thereto in a manner illustrated in Fig. 2. The strips 9' otherwise serve exactly the same function as the strips 9.

In Fig. 3 a further modification of the invention is illustrated wherein the strips 9 or 9' have the free margin thereof incised at intervals to provide tabs I 0' of different contour from that of the tabs l0. With certain classes of roofing this form of strip may be desired. It is used in the same manner as the strips 9 and 9'. In addition, in this form of invention I have shown the tabs H] as overlapping the interengaging terminals I! of the sheets or shingles. It is, of course, to be understood that although this form of the invention is shown only with the tabs II), it may likewise be used in connection with the tabs l0.

With this form of invention, the fastening means for the tabs II and H, strips 9 and 9' are all covered in a manner so as to effectively shed the elements therefrom and to avoid the accumulation of water or moisture around the same.

Although the shingles or sheets herein described are especially adapted for use on roofs, it is nevertheless to be understood that they may also be used in sidings. Also, although the shingles are shown to be fiat, it is nevertheless to be understood that they may likewise be corrugated, or of any conformation, if so desired.

It is also to be understood that while I have herein shown and described preferred forms of my invention, it is nevertheless to be understood that various changes may be made therein within the scope of the claims hereto appended.

What is claimed is:

1. In a roof construction, sheets of roofing laid in overlapping relation, the upper end of each sheet having a portion folded upon itself to form a nailing strip, the lower edge of the folded portion having tabs formed therein, certain of said 'tabs being bent upwardly upon the face of the overlapping sheet to hold the same to the roof.

2. In a roof construction, sheets of roofing laid in overlapping relation, an end of each sheet having a portion folded upon itself to form a nailing strip, the free edge of the folded portion having tabs formed therein, certain of said tabs being bent upon the face of the overlapping sheet to hold the same to the roof.
